The First Detection of Human Bocavirus Species 2 and 3 in Raw Sewage and Mussels in South Africa.

Human bocavirus (HBoV) has a global distribution and is associated with respiratory and enteric infections, particularly in the paediatric population. In this study, raw sewage and mussel samples were analysed for the presence of HBoV using nested PCR with primers targeting the VP1/VP2 junction. Amplification and sequencing of the 382 bp region followed by phylogenetic analysis indicated the presence of HBoV 2 in mussel samples and HBoV 3 in sewage samples. This is the first report describing the presence of enteric-associated HBoV in environmental samples from South Africa and in mussel samples from the African continent. The results signify the need for further studies examining the potential risk of foodborne transmission of HBoV and highlight the importance of continued screening to determine the prevalence and epidemiology of HBoV in South Africa.

The First Molecular Detection of Aichi Virus 1 in Raw Sewage and Mussels Collected in South Africa.

Aichi virus 1 (AiV-1) has a worldwide distribution and is associated with gastroenteritis in humans. In this study, raw sewage and mussel samples were analyzed for the presence of AiV-1 using reverse transcription-PCR (RT-PCR). Amplification and sequencing of the 3CD and VP1 genomic regions followed by phylogenetic analysis using selected genome sequences revealed the presence of AiV-1, genotype B. The results highlight the importance of further screening to evaluate the prevalence and epidemiology of this clinically important virus in South Africa.
